d7c2b98ead feedback: when creating a pipe fails, report also the reason
After commit 59bbc0b8 from five days ago (that made a divergent pipe
failure to be treated in the same way as the other two), this became
possible without having two different pipe-failure messages.

8b2114a25f rcfile: allow to bind M-[ (even though it is an escape-sequence starter)
The user had better avoid using the keystroke in a macro, but
when typing directly at a responsive machine there is no problem,
M-[ is a perfectly valid and recognizable keystroke.

c8a87b4d2a softwrap: initialize the 'extrarows' value for the magic line correctly
The make_new_node() function initializes 'extrarows' to a bad value
on purpose, to catch cases like this one where it doesn't get updated
properly.

6fa81ca5b8 formatter: force the mark off, to not crash by accessing empty cutbuffer
More generally, after invoking the formatter, the entire buffer should
be cut (to be replaced with the reformatted text) and not just the part
before the mark, because then everything after it would be duplicated.

This fixes https://savannah.gnu.org/bugs/?58879.

4940b02ae0 build: avoid compilation warnings by using memcpy() instead of strncpy()
When compiling with GCC 10.1.0 and -O2 -Wall, the strncpy() call
in measured_copy() produced two stringop-truncation warnings.

This addresses https://savannah.gnu.org/bugs/?58861.

312bcebf44 files: do not try writing to the status bar while not in curses mode

only when in curses mode.

3eff34b075 speller: re-enter curses mode before trying to report an error
If forking fails, we must first return to curses mode before we can show
an error message on the status bar.  (This additionally requires storing
the error number, because doupdate() apparently sets it to zero.)

40b03162c3 bindings: make <Alt+Backspace> delete a word backwards, like in Bash
It jars a bit that it is <Ctrl+Delete> that deletes a word rightward
and <Alt+Backspace> that deletes a word leftward.  But it's good to
also have a two-key keystroke bound by default to 'chopwordleft',
and not just the three-key <Ctrl+Shift+Delete>.

d0ad1e42d9 files: ignore only EPERM when fchmod() or fchown() fails
While ignoring permission errors from fchmod() and fchown() is okay
(since normal users are not always privileged to make such changes),
ignoring also more serious errors (like EIO) is not ideal.

A forward slash does not need to be escaped, and the backslash itself
should not be escaped: it serves to escape the star, to make it literal.

7157f5a3ce tabbing: properly terminate the answer when the sole match is a folder
When there is just one match when <Tab> is pressed, and this match
is a directory, then a slash is added to 'shared', overwriting the
terminating NUL character.  So, strcpy() cannot be used for copying
this 'shared' string, but strncpy() is needed, and the result needs
to be NUL terminated afterward.

This fixes https://savannah.gnu.org/bugs/?58826.

350115242d bindings: stop supporting <Esc> <Esc> <numeric slash> without NumLock
<Ctrl+numeric slash> does not invoke Go To Line, so it is fitting
that <Esc> <Esc> <numeric slash> does neither.  If some user does
want the double escape plus slash to work, they can use --raw.

(Also, if someone really uses <Esc> <Esc> <numeric slash>, they
probably also type the desired line number on the numeric keypad,
and for that to work they needed to have NumLock engaged, and in
that case the double escape plus slash will work fine.)

(Getting rid of this numeric-slash support makes the three-escapes
case very similar to the one-escape case, allowing the first to be
folded into the latter in the next commit.)
